Facebook Wedge
Facebook Wedge is a Top-of-Rack (TOR) network switch hardware platform (data center networking) developed by Facebook as part of its disaggregated, open hardware strategy for hyperscale data centers.
- Top-of-Rack Switch (ToR) hardware platform for Facebook data centers (data center networking).
- Designed to run a disaggregated network Operating System (OS) separate from the hardware (network operating systems).
- Implements high-density Ethernet switching for intra–data center traffic between servers and aggregation layers (LAN switching).
- Developed within Facebook’s Open Compute Project hardware efforts to enable open, vendor-neutral switch designs (open hardware infrastructure).
- Targets large-scale, software-controlled network fabrics for cloud and web-scale environments (software-defined networking context).
More About Facebook Wedge
Facebook Wedge is a hardware platform for TOR network switches (data center networking) that Facebook introduced as part of its move toward open and disaggregated network infrastructure. It is used in Facebook’s data centers as the switching element that connects racks of servers to the broader data center network fabric. Wedge is positioned within Facebook’s broader Open Compute Project hardware portfolio, which focuses on open specifications for data center servers, storage, and networking equipment (open hardware infrastructure).
The central purpose of Facebook Wedge is to separate the network OS from the underlying switching hardware (network operating systems), creating a disaggregated model in which hardware and software can be sourced, developed, and updated independently. This approach enables operators to run a network OS of their choice on the Wedge platform, subject to compatibility with the hardware and switching ASICs. The design aligns with Facebook’s use of software for centralized control, monitoring, and automation of the network fabric (network automation).
As a ToR platform, Wedge provides high-density Ethernet ports (LAN switching) to support large numbers of server connections within a rack. It forwards traffic between servers and uplinks to aggregation or spine switches, operating as a foundational element in a leaf-spine data center architecture (data center fabric). The hardware design is oriented toward high-throughput, low-latency packet forwarding and supports modern Ethernet switching features expected in hyperscale environments, such as VLANs, link aggregation, and standard routing and switching protocols when enabled by the installed network OS (enterprise networking).
Enterprises and institutional users that follow Open Compute Project specifications can adopt designs derived from Wedge to build disaggregated switching environments. In such deployments, Wedge-like platforms can interoperate with other data center systems via standard Ethernet and IP protocols (network interoperability), while management and control are provided through the chosen network OS and orchestration stack. This model fits into Software Defined Networking (SDN) strategies where control-plane logic and automation tools are decoupled from the physical switch hardware.
Within a technical directory, Facebook Wedge aligns with categories such as data center networking hardware, open hardware switch platforms, and disaggregated network infrastructure. It is relevant to roles focused on network architecture, infrastructure engineering, and cloud-scale operations that require open, programmable, and vendor-neutral switching platforms integrated into automated data center environments.
